SPECIFICATION forming part of Letters Patent No. 676,529, dated June 18,1901.

Application tiled March 6,1900. Serial No. 7,452. (No model.)

To all whom it may concern:

. Be it known that we, HUGH K. BROWNING and MICHAEL J. DALY, citizens ofthe United States, residing at Chicago, in the county of Cook and Stateof Illinois, have invented a certain new and useful Improvement inWindows, of which the following is a specification.

Our invention relates to improvements in windows and the like, and hasfor its object to provide a new and improved construction of thisdescription.

Our invention is illustrated in the accompanyin g drawings, wherein-Figure 1 is a view of a window embodying our invention. Fig. 2 is asection on line 2 2, Fig. 1. Fig. 3 is a section on line 3 3, Fig. 1,the two sashes of the window being closed. Fig. 4. is a section on lineat 4:, Fig. 3, with the guide-pieces in their normal position. Fig.

5 is a View similar to Fig. 4 with the guidepieces retracted.

Like letters refer to like parts throughout the several figures.

One of the objects of our invention is to provide a window or the likeso constructed that both the inner and outer faces are easily accessiblefrom within the building for cleaning and the like; In the ordinarywindow it is necessary to clean the outer surface of the window from theoutside, While with our the case.

to the sides of the window-sash. The pieces E are provided withprojecting parts E,which work in slots or the like F. in the parts Eassociated with the window-frame. These parts E may act as guides orholding-pieces which hold the window-sash in place and between which thewindow-sash slides. It is of course evident that any desiredconstruction for this purpose may be used, and we have only attempted toshow a simple and conven ient construction. In the construction shown,for example, in Fig. 3 the parts E are shown as hollow, having an openspace It extending longitudinally therealong. The piece E is provided atits end with an enlargement E which is larger than the slot E so thatwhen the parts are assembled the pieces E of the hinges will be held inplace, but free to slide up and down along the slots E Some suitablemeans is provided for inserting the enlargements E in the parts E Thismay be done by cutting away the inner face 3. of said partsas, forexample, atE Fig. 2. The parts E are preferably made of iron, althoughit is of course evident that wood or any other material may be used. Thesashes A and B are provided on their hinged sides with suitable cordsand weights in the ordinary man ner,the cords A B being connected to theweights A B, which move in a suitable hollow in the frame, as iscustomary in such cases. At the other side of the frame the guide-piecesbetween which the lower sash is confined are made movable, so that theymay be easily retracted to free the lower sash and permit it to swinginwardly on its hinges, as shown in Fig. 1. This result may be obtainedin any desired manner. To have shown one simple and ef- -ficient meansor retracting device for accomplishing this result. In this constructionwe have connected the guide-pieces F and G together (see Fig. 3) andprovided a device for moving them inwardly past the edge of the sash, soas to free said sash. It is of course evident that it is only necessaryto have these guide-pieces movable for a length substantially equal tothe height of the lower sash, thus permitting a movement of a sufficientlength of these guide-pieces to free the sash. Any suitable means may heused for moving the guide-pieces. As here shown, We have provided acrank I'I, having one end I-I mounted in the side of the frame and theother end mounted in a suitable bearing H attached to some fixed part.This crank is connected with the guide-pieces F and G by means of thedevices H A suitable space H is provided to permit a sufficient movementof the parts to free the sash. We prefer to provide a thumb-piece H ,bymeans of which the crank is rotated. In Fig. 1 we have shown two cranks,one near the bottom and one near the top of the lower sash. Thisconstruction, while not necessary, permits the entire length of theguide-pieces to be easily and quickly retracted and forms a veryconvenient arrangement. The guide-pieces F and G may be made in onecontinuous U-shaped piece, if desired, or they may be made in separatepieces and fastened together.

As shown in Fig. 3, the side piece I of the frame is slotted for adistance equal toor some greater than the height of the lower sash, andthe guide-piece .15 projects through this slot. We have shown theguide-piece G as being attached to the piece I, as this constructionpermits the guide-piece G to be given any desired shape in order toconform to the decorations of the room in which the window is located.As shown in Fig. 2, the guideways in which the lower sash movesproject'somewhat beyond the upper edge of the upper sash when in itsnormal position, sothat when the lower sash is lifted upwardly, as shownin dotted lines, its lower edge will be above the upper edge of theupper sash when said latter sash is at the bottom of the window, thuspermitting the upper sash when at the bottom to be swung inwardly on itshinges Without engaging the lower sash.

The use and operation of our invention are as follows: A window providedwith our invention normally differs in no particular from an ordinarywindow. The upper and lower sashes may be moved up or down, as in anordinary window, and are held in any position by means of weights.During this movement the pieces E of the hinges are free to slide up anddown in the slots E and the parts are adjusted so as to permit an easyand proper movement. We have found in practice that entire satisfactionis obtained by having the cords at one side of the Window only. If nowit is desired to wash the outer face of the window, the lowersash ismoved to its lower position, and the guide-pieces are then retracted bytaking hold of the thumb piece or pieces H and moving them, so as torotate the crank or cranks. WVhen the guidepieces F and G move inwardlypast the edge of the sash, the sashmay be swung inwardly on its hinges,as shown in Fig. 1, and the outer face cleaned with perfect ease andsafety. When the lowersash is cleaned, it is moved back upon its hingesto its proper position and is then moved upwardly to the position shownin dotted lines in Fig. 2. The upper sash is then moved downwardly 'andis in turn swung inwardly on its hinges, so that its outer face may becleaned. After the upper sash is cleaned it is swung back upon itshinges and moved to its proper position. When the guide-pieces F and Gare moved outwardly by means of the thumb piece or pieces H, the windowis in its normal position and the sashes are held in theirproper place.

It will thus be seen that we have here a simple andefficientconstruction, which permits the'outer face of the window to beeasily, quickly, and safely cleaned, and that the mechanism by whichthis is accomplished is simple, durable, and efficient and can be supplied to the window at very little cost.

The pieces F and G, shaped andprojecting as they do, we have calledguide-pieces;

but they are combined togetherto produce a single guide piecawhich is ineifect U-shaped, and we have so alluded to this construction in theclaim.

We claim- A window, comprising two sliding sashes, each provided at oneside Witha suitable cord and weight, a hollow slotted guide-pieceassociated witheach of said sashes, a hinge attached to each sash at theside near the hollow guide-piece, each hinge provided withv a projectingsliding part which extends into the-associated hollow guide-piecethrough the slot, so as to permit the sashes to slide up and down, amovable U-shaped guide-piece at the opposite side of the window-frame,said guide-piece being equal or greater in length than the height ofeither sash, a fixed frame portion opposite the window-sash and betweenthe arms of said U-shaped piece, a

crank attached to said movable guide-piece and adapted when operated toretract it and free the sash confined between said guidepieces, so thatit may be moved inwardly on its hinges, the guideways in which one ofthe sashes moves beinglonger than twicethe height of said sash, so thatsaid sash may be moved to a position where it will be entirely free:from the other sash, when said latter sash is opposite said movableguide-piece.
